If @Philippe683's side of the story is correct then it seems very unfair. I had a guest who had an accident in the bed, but was kind enough to tell me about it and give me £20 for cleaning. This was not two drops of blood, but a lot of blood on the duvet cover, duvet, sheets, mattress protector and the mattress topper underneath it. It took a lot of washing and time, but it did all come out with some regular stain remover.
However, in my experience, there seems to be a big disconnect between the damage that hosts think a guest has caused and what the guest thinks about it. Very recently, I had two girls stay who were generally a bit clueless and careless. I mean they left the front door unlocked, bathroom taps running, big clumps of hair stuck on the bath and on the shower screen in shared bathrooms, used an absurd amount of toilet paper and left it spilling out of the bin rather than putting it inside properly, disturbed another guest by banging on the door of the shared bathroom she was using until she came out, that sort of thing.
I would have overlooked it all, but after they left and I went in to clean the room, I noticed the silk curtains were soaking wet and then realised that they had broken the valves on both radiators, causing them to leak. The water came through the ceiling below, staining it, and also soaked a vintage velvet chair.
Now, I didn't ask these guests for any money (pretty generous, right?) and told them I would try to cover it from my own home insurance, but they got mad at me anyway and TOTALLY denied that they could have caused any damage because they were "young girls" and that if they did break something, it must have been "just waiting to happen". Not true. The valves are very expensive, high quality and the engineer who came to fix them commented, unprompted, that they were in very good condition. They do not break for no reason and especialy not two at the same time and in the same way.
Still, these girls would not admit any responsibility. Just goes to show how we see things from the perspective that suits us. I am not saying that this is the case with @Philippe683, but perhaps the host genuinely feels that he caused 250 Euros worth of damage.
